lignin-derived substrates have emerged as desirable biorenewable chemical feedstocks for coupling reactions. A radical-mediated conversion of phenol derivatives to anilines is reported, using unfunctionalized hydroxamic acids as the N-centered radical source. The applicability of this triethylphosphitemediated O-atom transfer approach, which tolerates a range of steric and electronic demands to naturally
A diversity-oriented synthesis of bioactive benzanilidesviaC(sp2)–H hydroxylation has been studied. The reaction demonstrates excellent regioselectivity, good tolerance of functional groups, and high yields.

A conceptually new and synthetically valuable radical Smiles rearrangement reaction is reported under undivided electrolytic conditions. This protocol employs an entirely new strategy for the electrochemical radical Smiles rearrangement. Remarkably, an amidyl radical generated from the cleavage of the N–O bond under reductive electrolytic conditions plays a crucial role in this transformation. Various
